Internal error during ALE transfer of inspection methods

What causes this issue?

When transferring inspection methods with ALE, you tried to send
several inspection method data records that do not logically belong
together in one unit.
This function is not supported. Inspection methods with different
inspection method numbers or other plant assignmnents must always be
sent in different transfer units.
The following inspection methods or plant data that are not identical
are affected:
Inspection method (old): &v1&,,,,,,Inspection method (new): &v2& and
Plant (old): &v3&,,,,,,,,plant (new): &v4&

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

System Response

The system does not save the incoming inspection methods.

How to fix this error?

This error can occur for example, because of an inconsistency. Try
again to transfer the inspection methods.
If the problem occurs again, see your system administrator.
